What happens if the CO's arrival announcement is missed?

When the commanding officer's arrival announcement is missed, the formal announcement cannot be substituted. This is significant because the arrival of the commanding officer is an important event that underscores the chain of command and maintains the proper decorum on the ship. The formal announcement serves to inform all personnel of the CO's presence, ensuring that appropriate respect and acknowledgment are given.

Reinforcing the importance of protocol, if the announcement is missed, it cannot be corrected by simply noting it in the log or making a less formal announcement later. This ensures that the integrity of the command structure is upheld and that all personnel are aware of the CO’s presence as a marker of authority and leadership on board.
